Thanks Chas
Sorry I didn't answer the questions in your first post but frustration took over and I walked away for a little while. The transformer does not have any shorts. I had the radio on for more than an hour while checking voltages and poking around and the tran. got a little over room temp. Warm to the touch.
There is no Candohm in this radio and I'm still not sure how to check if a cap or resistor is leaking to chassis. Something I have still got to learn.
After checking voltages with my vtvm,( which is an Eico 232)it was a little higher but still below the specified voltage. Recommended 180 v dc plate voltage and with the vtvm I got 156 v. This difference was consistent thru the set. I also have a Fluke with 1000ohm/volt.
I obtained a 40-180 chassis which is similar to the 40-190. I checked my wiring and the installation of components to it and they all seem right. The only thing changed in the -180 were the Ecaps and 2 wax caps.
As far as checking the grounding everything is riveted as far as chassis grounds. I went thru and tried to get a connection on all the ground rivets with a screwdriver while the set was on and got nothing.
So my next test is to check my current consumption on the B circuit using your guidelines.
My prowess is waning along with my confidence but I'll keep trying.
Thanks again
Dick
